JCY series contact angle measuring instrument is a standard instrument for measuring the contact angle surface energy of solids and the surface tension of liquids. The test method adopted is image analysis method, through standard image analysis , CCD camera and image acquisition system are used, and at the same time, the contact angle value data is automatically analyzed by software. The application environment of the image values of various shapes of objects. The force measurement method has higher requirements for the uniformity and flatness of the material. The image analysis method can be used to test the surface tension value of samples under high temperature conditions, such as melted polymers.
1. Using a new CCD camera system, the image of the measured droplet can be clearly displayed on the computer screen for high-precision contact angle analysis and measurement. The highest resolution of the camera: 1280×1024, frame rate: 15 or 45/ Second
2. High-precision level control, hardware level correction and software level correction (curve baseline correction) combined to achieve more accurate level alignment of the contact angle curve
3. The aviation aluminum body is adopted, which is both light and stable
4. Automatic calculation of contact angle, left and right contact angle comparison function
5. Dynamic contact angle analysis system, including analysis of contact angle changing with time, advancing angle/receding angle, inclination angle and roll angle analysis
6. Estimation of solid surface energy: Fowkes one-liquid method, Owen two-liquid method, Zisman method, Acid-Base method and other surface free energy estimation
7. The software comes with a brightness correction function to modify the image brightness
8. Various test methods: pendant drop method, sessile drop method (static drop method);
9. Surface tension measurement: Pendant drop method (Young's equation) to measure liquid surface tension
10. Database management functions: query, backup, compression, export EXCEL form
11. The operation calculation software is based on WIN XP, VIAST system
